    Indicator # 2 - Date when the pollen season ended by pollen source             Print PDF


    Pollen Risk Communication Message: Pollen grains are released by trees in the spring, different types of grass in summer and a variety of weeds in fall.  Ragweed pollen is also released in the fall, but it is more allergenic than other pollen types.  Because of climate variability we now know that higher temperatures and more carbon dioxide result in increased pollen in the air.  Children and older adults who have asthma, allergic rhinitis or other respiratory diseases have more severe allergic reactions as total pollen grains in the air increase or when ragweed pollen is produced in the fall.  Pollen influenced allergic and respiratory reactions are even worse in the summer when ozone and/or fine particulates in the air are also higher.  Research has shown that higher pollen levels increase emergency department visits and inpatient hospitalizations due to asthma, hay fever and other respiratory diseases.  Prevention efforts can include seeing a health care provider before the start of the pollen season or when breathing problems become worse when pollen spores increase.  Persons can decrease their exposure to pollen by not going outdoor, staying in a home or automobile with the windows closed and the air conditioner on, taking a shower to remove pollen from around the nose and mouth, and changing clothes.  For more information about pollen and health see the MTN pollen indicator page.

     Data sources for this indicatorà

    • Determine the last day, also recorded as mm/dd/yyyy, in which counting took place for any pollen source in the calendar year.
    • The end of the pollen season should be recorded for the four pollen sources, trees, grasses, weeds, and ragweed, separately.
    • Note: If a pollen station makes pollen readings throughout the calendar year, the last day should be December 31. Likewise, if the last pollen reading was made on a date prior to December 31, then record on that date as the end date for the pollen season.
